YSI EC300A Conductivity/Salinity/TDS/Temperature Meter, Meter Only

The YSI EC300A portable meter provides conductivity, specific conductance, salinity, TDS, and temperature readings for water quality testing applications, as well as automatic temperature compensation, an LCD screen, and a four-electrode conductivity cell. This meter has automatic temperature compensation (ATC) for accurate readings in fluctuating temperatures, and pushbutton calibration capabilities. Onscreen tutorial messages for calibration and measurement procedures display on a large LCD screen for ease of viewing. The meter's four-electrode conductivity cell is designed for field use. It has a memory function that can store up to 50 data sets and calibration backup that preserves settings when the power is off. The unit operates on a single 9V battery, and turns off automatically after 30 minutes of inactivity to conserve battery life. It has a low-battery indicator that signals when the battery needs to be replaced. The meter's sealed housing is Ingress Protection certified IP67 for protection against dust and short periods of immersion in water. It comes with a 9V battery and instructions.

*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

A multiparameter meter is a benchtop or handheld device that can take multiple readings on a single sample. It measures parameters such as the pH level (acidity or alkalinity of a substance), conductivity (the amount of salts or other compounds present in water), dissolved oxygen (DO, the amount of oxygen in a liquid), temperature, total dissolved solids (TDS, anything present in water other than the pure water molecule and suspended solids), salinity, resistivity, and oxidation reduction potential (ORP). Applications for multiparameter meters include water testing, pharmaceuticals, agriculture, winemaking, water-treatment plants, and acquaculture. Devices with a benchtop body are often used for indoor laboratory use or in a manufacturing setting; handheld, portable devices are typically used for fieldwork. Sensors are used with a meter to measure the parameters of a substance.

YSI manufactures instruments, sensors, and software for environmental water quality monitoring and testing. The company, founded in 1948, is headquartered in Yellow Springs, OH.
